The present invention relates to electric mixers and more particularly to multiple revolving mixers.

The primary object of the invention is to pro- 5 vide a unitary construction capable of mixing a plurality of drinks simultaneously and independently. p

A further object of the invention is to provide a multiple revolving mixer wherein a multiplicity 10 of independently operated motors are supported within a casing and having the mixing elements depending from said casing.

A still further object of the invention is to form a rotary support for a hollow casing from 5 which are supported a plurality of independently operated motors, the rotary support being provided with means for supplying current to the various motors.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawings which form part of the application.

In the drawings:

25 Fig. 1 is afront elevational view of the mixer having certain parts broken away to illustrate specific details.

Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. 1.

30 Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1; and

Fig. 4 is a transverse sectional view taken on line 4-4 of Fig. 1.

Referring to the drawings, the numeral 5 in- 35 dicates one part of the base for supporting the mixer and the numeral 6, the other part of the base which is rotatably mounted on said base 5 thru the medium of ball bearings or the like 1.

Any fastening means, such as the nut and bolt 8,

40 ,may be used for securing the two parts together.

Carried by the base member 5 are a pair of circular contact rings 9 and I which are suitably insulated from the base member and connected to a wall plug thru the medium of the connect- 45 ing means I l. Current is received thru the means II and carried to the contact rings 9 and I0 and thence to the motors, to be later described.

A hollow tubing l2, preferably hexagonal shaped, is suported by the molding l3 which 50 forms an integral part of thebase member 6.

The tubing 12 is frictionally held within the molding or flange l3 at its lower end and likewise to the flange M at its upper end, which forms a part of the motor casing l5. This arrangement pro- 55 vides a unitary construction of the casing [5,

tubular member l2 and base member 6, respectively, so that the entire assembly will rotate on the base member 5. A plurality of supporting brackets I6 are secured to the tubular member l2 for supporting the mixing cups l1.

The means for supporting a plurality of motors in a closed compartment, comprises the casing l5, above referred to. The motors l8, of which there are six illustrated in Fig. 2 of the drawings, are supported in any desired manner, as, for example, the bracket l9 and supporting clip 20. Current is supplied to the motors from the switch plate 2| having direct contact with the motors thru the wiring 2| and the contact plates 9 and ID thru the wiring 22, it being understood 15 that conducting lines extend from the circular contact plate I!) to each of the motors and likewise to the switch plate 2|, completing the circuit.

Depending from each motor l8 and thru the casing i5 is the rotary mixing element 23. Each motor and its mixing element 23 operate independently when the member 24 is contacted by the mixing cup H. An electrical switch is connected to each motor, each switch being of the plunger type and comprising a vertically mov- 25 able arm 25 for effecting contact with the contact element 26 when engaged by the upper end of the mixing cup H. The arrangement of the cup with respect to the switch element 24 is illustrated in Fig. 1 of the drawings.

From the above description it will be noted that the entire construction may be rotated on the base member 5 so as to bring into use either or all of the mixing elements and their respective motors. The spring pressed contacts 21 are normally in contact with the contact ring In during the rotation of the mixer. A suitable handle means 28 may be employed for rotating the assembly.

If desired, the globe 29 may support and retain a lighting fixture for illuminating and advertis ing purposes, current being supplied from the switch element 2 l.

It is to be understood that this improvement is capable of extended application and is not confined to the exact showing of the drawings nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

What is claimed as new is:

1 A drink mixer comprising a base, said base being formed of two parts one rotatably mounted on the other, a flange extending from and integral with said base, a hollow supporting column mounted within said flange, a casing secured to said COIUUIII, a plurality of electric mixing motors supported in said casing, circular contact rings carried by said base, and means extending through said column for connecting said rings with said motors for operating the same upon contact of a mixing cup with a switch.

2. A drink mixer comprising a base, said base being formed of two parts one rotatably mounted on the other, means for supporting a hollow col- JULIUS F'LAUM.
